3nh NS808 Handheld Spectrophotometer (400~700nm; 10nm)

3nh NS808 Handheld Spectrophotometer (400~700nm; 10nm)

In industrial manufacturing environments, maintaining consistent color uniformity between incoming and outgoing batches is the most visual metric of product quality. However, basic colorimeters that use outdated color filters are highly susceptible to major errors when factory temperatures fluctuate, and they remain helpless against metamerism (a phenomenon where colors appear identical under factory lighting but completely different under natural light). The 3nh NS808 handheld spectrophotometer was developed as a breakthrough solution—bringing ultra-fine 10nm diffraction grating spectral separation technology into a portable device, helping businesses standardize their quality management processes in the most scientific way.

Overview of the 3nh NS808 Spectrophotometer

The 3nh NS808 is a professional handheld spectrophotometer meticulously researched by the 3nh brand to optimize mobile measurement capabilities across factories and warehouses. The device utilizes an internationally standardized d/8 optical geometric structure (diffused illumination, 8-degree viewing angle), fully and strictly complying with the rigorous regulations of the International Commission on Illumination (CIE No.15), ISO 7724/1, ASTM E1164, and DIN 5033.

Equipped with a highly sensitive dual-path CMOS matrix spectral sensor and a premium optical diffraction grating, the NS808 precisely extracts the reflectance curve of each light wavelength from 400 nm to 700 nm with an ultra-fine 10nm pitch interval. The instrument delivers stable measurement results with excellent repeatability, completely outperforming conventional colorimeters on the market.

Key Features of the 3nh NS808

💡 Ultra-Fine Spectral Scanning Technology (400~700nm; 10nm Interval)

The core strength of the 3nh NS808 lies in its continuous spectral scanning range that completely covers the visible light spectrum with an extremely small pitch interval of just 10nm. This technological upgrade allows the device to capture the detailed spectral reflectance curve of materials, detecting the smallest shade variations in any color spectrum, which thoroughly controls metamerism and ensures maximum objectivity in measurement data.

💡 Simultaneous Integration of Dual Premium Measuring Modes: SCI & SCE

The advanced optical system of the NS808 allows technicians to perform deep analysis of material surface characteristics via two measuring modes:

• SCI (Specular Component Included): Measures the actual intrinsic color of the material, eliminating all interference caused by matte surface gloss or the roughness of powder coatings and plastic resins.
• SCE (Specular Component Excluded): Measures the actual color appearance as seen by the human eye, perfectly serving product aesthetic evaluations according to real visual perception.

💡 Standard Flat Measuring Aperture and Precise Positioning

The NS808 features an industry-standard flat measuring aperture (typically configured at Φ8mm), which is the most optimal size for the vast majority of manufactured materials. The flat aperture design allows it to fit completely flush against large, flat product surfaces, eliminating external stray light interference. Combined with a clearly defined illuminated positioning spot, technicians can easily align the aperture with the exact center point to be measured.

💡 Comprehensive Color Spaces and Ultra-Fast Pass/Fail Evaluation

With a single gentle button press taking less than 1.5 seconds, the sharp industrial graphic display of the NS808 immediately presents intuitive results:

• A complete set of international color spaces: CIE Lab, XYZ, Yxy, LCh, RGB…
• Advanced color difference formulas: Delta Eab, Delta E00, Delta Ecmc, Delta E94.
• Smart tolerance warning mode: Automatically compares the measured sample with the standard sample and instantly displays a Pass or Fail result based on the allowable tolerance range, helping assembly line operators rapidly screen for defective parts directly on the floor.

💡 Unlimited Connectivity and Automated Reporting

Via a high-speed USB data transfer port, the NS808 effortlessly synchronizes data with professional PC-based color management software. The software supports businesses in storing thousands of standard sample datasets, managing digital color libraries (Pantone, RAL), tracking shade variation trend charts across production batches, and automatically exporting professional quality control reports (QC Reports) in PDF/Excel formats to send to partners.

Practical Applications of the 3nh NS808

Thanks to its compact portability, fine 10nm spectral scanning band, and maximum reliability, the 3nh NS808 handheld spectrophotometer is widely applied in various fields:

• Plastic Industry: Controlling the color uniformity of incoming masterbatch resins, plastic preforms, and the surfaces of large flat molded plastic products such as household plastic panels, electronic casings, and automotive plastic components.
• Paint, Coating & Plating Industry: Inspecting color deviations in powder coatings, coil coatings, protective finishes on metal sheets, construction materials, and architectural wooden furniture.
• Printing & Packaging Industry: Checking color variations of printing ink on paper boxes, flat corrugated cartons, and embossed decal labels, ensuring absolute compliance with brand identity logo colors for partners.
• Textile & Leather Industry: Rapidly evaluating color quality, color fastness, and color consistency between flat dyed fabric rolls before moving to mass cutting and sewing lines.
